IMPROVEMENT IN BOATS' RUDDERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, WrLLrAM C. LAW, of the cit-y, county, and State of' New York, now temporarily residing at Ningpo, China, have invented a new and useful Improvementin Rudders and I do hereby declare that the following is a full, clear, and exact; description thereof, which will enable others skilled iu the art to make and use the same, reference being had to the accompanying drawings forming part of' this specification, in whichn Figure l is a side View of my improved rudder, as attached to a vessel.

Figure 2 is detail sectional Yiew of the same, taken through the line a: 9;, tig. 1.

Figure 3 is adetailseotional View of the same, taken through the lines y y, tig. 1.

Figure 4 is a detail sectional View, taken through the line s z, fg. 1.

Similarl letters of reference indicate corresponding parts. f

My invention has for itsV object toimprove the manner of hanging and the -construction of ruddcrs for ships, boats, and other vessels, so as to make them more easily shipped, less liable to be accidentally unshippe'd, and so that they will serve as a center-board for sail-boats and It consists in the manner of hanging theJ rudder and in the construction of the body ot' the rudder, as hereinafter more fully described.

A represents the stern cfa boat or other vessel.

B is a rod, which is connected with the vessel A by two or more brackets, O 'D, formed solidly upon or Afirmly attached to said rod B.

The shank ofthe bracketG, at the lower end ot' the rod B, is made broad, andthe shanks of the upper bracket or brackets D are made narrow or thin, as shown in tigs.' 2 and 4.

To the inner edge of the rudder E are attached two or more eyes or sockets, F G, which are formed withv strapsppassing along the sidesof the rudder E, and securely rivetedor bolted to said rudder.

The lower socket or sockets F are slotted in aline with the plane of `the rudder E, as shown in iig. 3, and the upper socket G is made without a slot, as shown in g. 2.

By this construction of the hanging device, the rudder can be readily shipped in the roughest sea, and it will be scarcely possible for it to become accidentally unshpped, as to unship the rudder it must be raised vertically while in a line with the line of the keel of the vessel.

For sail-boats and other small vessels, the bodyof the rudder may be extended so as to project below the vessels keel, as shown in tig. 1, so that it may serve both as a rudder and as a center-board. In this case the tenon c ofthe rudder, upon which the tiller H is placed, is made long, and with a series of holes to receive the pin by which the said tiller is secured to it, so that the. rudder may beadjusted in any desired posit-ion.

' By'this construction, should the boat run aground, the rudder will rise above the keel wit-hout becoming unshipped.

Having thus described my invention, v

I claim yas new and desire t'o secure by Letters Patenty I 1. The continuous rod B and brackets O D, combined with the 1 slotted sockets I? F and unslotted socket G, as and for the purpose described.

2. The elongated rudder E, extending below the keel, and having a long tenou, e', perforated at intervals, as and for the purpose described.

The above specification of' my invention signed by me thisl day of 1869. l
